I don't have a magnifying glass, sorry. It's either sterling silver or 10k white gold. I have two pendants one is gold one is silver. Not sure which one this is.
That's ok. To be honest I am not sure. I have two very similar diamond heart pendants. I believe this one is sterling silver. Could be white gold, but I can never remember which one is which. It is one or the other, I know that much. =)
